HV Subminiature-D Bulkhead Feedthroughs

The HV (High Vacuum) Bulkhead-D feedthroughs were developed for high-vacuum flat-chamber-wall applications where conventional ISO NW KF or LF flanges are either not available, or just not practical.  Our universal 2x3.5 inch rectangular flanges, the Bulkhead-D flange, accommodates standard 9, 15, 25 or 50-pin subminiature-D feedthroughs, and shares the same gasket and fastening accessories... providing simple and convenient interchangeability.

See individual products for instructions on how to prep your vacuum chamber for use with the new D-Sub Bulkhead feedthroughs.
